COMBINED ANTIRATTLER AND WEATHER; STRIP FOR WINDOWS.

Application fl-led February 7, 1928.- Serial No. 252,500.

The present invention relates to a combined anti-rattling and draftpreventing device for doors, windows and the like and has for its mainobject to provide metal strips for this purpose, which are so shaped andfashioned that they will practically close up all openings between theframe and the sash with out increasing the friction during the openingor closing of the latter. This obviates all use of felt or wooden stripswith the accompanying swelling and: bind ing during damp weather orsticking from painting.

In order to accomplish this tightening without binding the metal stripsare I'urnishedwith co-operating. tongues whi-ch tend to press the sideflanges of the metal strips against the sash faces or grooves providedtherein.

Another advantage over ordinary weather strips is that these metalstrips are practically everlasting and consequently need no renewal andindefinitely retain their elasticity and consequent anti-rattling anddraft-preventing properties.

In the accompanying drawing one embodiment of the invention isillustrated and Fig. 1 showsa transverse section through one side of thewindow casing andthe sashestherein;

Fig. 2, a similar section of a metal weather strip for the sides of thewindow;

Fig. 3, a side elevation of Fig. 2;

Fig. 4, a vertical section through the top portion of "the window casingand upper sash;

Fig. 5,. a transverse section of a metal weather strip for the top andbottom of the window and Fig. 6 a front elevation of Fig.

In the drawing, reference numeral 10' rep resents the p'ully still orjamb of the casing,

' numeral 11 the blind stop and numeral 12 the inside stop. The upper orouter sash is represented by numeral 13, the inner sash by numeral 14:,and their window panes by numeral 15. In a, rabbet 161furnished in thepulley still 10 fits a parting strip or bead 17, which projects inbetween and separates the two sliding sashes, while the outer face ofthe upper sash 13 contacts with the blind stop 11 and the inner face ofthe sash li contacts with the inside stop 12 in the usual manner.

The weather strip is preferably made from flexible sheet metal cut intostrips and bent as best seen in'Figs. 2 and 3, into a substantiallyrectangular cross section which fits around the parting head 1 and inthe rabbet 16. The side wall 21 of this strip is bent inwards across theparting head 17, to form a tongue 22 slightly narrower than the bead inorder not to bind with the opposite side wall 23. The latter is bentoutward to form a flange 24 and then doubled on itself and carriedacross the tongue 22, terminating with a second flange 25, the edge ofwhich may be rolled as at 26. In thismanner the metal strip takes theform of a closed U-s-ha'ped cl-Iannel having oppositelyprojecting-flanges 24 and'25.

In order to increase the tightening property oi the strip, its-sidewalls 21 and 23 may be made slightly diverging, and the tongue 22 bentso as to exert a slight pres sure against the transverse flange 25, asclearly illustrated in Fig. 2.

The parting bead 17,'together with the metal strip 20 is secured in therabbet 1G by means of nails or screws 27 in the usual manner. The uppersash 13 and the lower sash 14 are each provided with a longitudinalgroove 28 and 29 respectively, adapted to receive the flanges and 26, asbest seen in Fig. 1. As the flanges spring apart, they will tend toseparate the sashes thereby, pressing them against their respectivestops ll and 12, thus elin'iiua-ting rattling and all draft. I

In Figs. 4, 5 and 6 is shown how the weather strip is applied at thetop' and the bottom of a window, and reference numeral 13 as beforerepresents the upper or outer sash, numeral 30 the top jamb, numeral 31the blind stop and 32 the top, parting bead fitting halfway down in arabbet 33 furnished in the jamb 30.

The top weather strip 345 issimilar in construction to the side strips20 and works on the same principle, but the side walls 35 and 36 arebent towards the middle of the channel and the wall thus forms a tongue37 terminating with a rolled edge 38. The other side wall 36 of thestrip has its bent portion 39' doubled upon itself to form a knee-shapedflange 40 hanging down substantially, perpendicular from the top jamb 30and spaced from the parting head 32. The knee-shaped flange 40terminates with a tongue ll preferably within the channel and has also arolled edge 42. The latter contracts with the other tongue 37 of the topweather strip tending to press the latter tongue outwards or away fromthe parting bead 32, or against the face of the sash 13. The downwardlyprojecting portion of the knee flange 40 engages in a. narrow groove 4-2cut in the top face of the sash 13, see Fig. 4. The parting bead 32holds the top weather strip 34 in position in the rabbet 33 and isitself secured therein by means of nails or screws a3 in the usualmanner.

It will now be evident that when the outer sash 13 is in its upper orclosed position, it will be gripped tightly by the knee flange 40 andthe tongue 37 but as soon as the sash is lowered it will be free fromthe said parts.

Likewise the T-shaped side strip will en gage with its flange in thegroove 28 of the outer sash 13, on the one hand, and with its flange 2ain the groove 29 of the inner sash 14. The tongue 22 pressing againstthe flange 25 will then co-operate therewith to press the flanges firmlyinto their respective grooves in the sashes thereby preventing rattlingand draft.

A weather strip 34 may also be provided at the bottom of the inner sash.14. In that case a groove is provided at the lower face of the sash andthe weather strip is placed with its knee flange pointing up instead ofdown as in the former case.

It is to be understood that the details of construction and arrangementof parts may be varied widely without departing from the spirit of theinvention, and we do not wish to limit ourselves to such features exceptas may be required by the claims.

We claim:

1. A weather strip for windows and the like, comprising a folded memberof flexible sheet material having a projecting side flange adapted toengage in a groove formed in the sash of the window, and meanscooperating with the flange to make the flange fit tightly in saidgroove; said means includ ing inter-engaging wings on said flange andthe body of said member.

2. A weather strip for windows and the like, comprising a folded memberof flexible sheet material, said member having a channel shaped bodywith transversly projecting flanges, and means cooperating with theflanges to make them engage tightly in corresponding grooves of thewindow sashes.

3. A weather strip for windows and the like, comprising a folded memberof flexible sheet material, said member having a channel shaped bodywith transversely projecting flanges, and means cooperating with theflanges to make them engage tightly in corresponding grooves of thewindow sashes, said means including interengaging wings on flanges andbody of said member.

4. The combination with a window frame and sliding sashes, of channelshaped metallic weather strips therefor; each of said strips having abody portion, and transversely projecting flanges and means for flexingthe flanges to engage tightly in corresponding grooves in the sashes,and a paring bead adapted to retain the body portion in a rabbetprovided therefor in the frame.

5. The combination with a window frame and sliding sashes, of channelshaped metallic weather strips therefor; each of said strips having abody portion, and a kneeshaped side flange and means for flexing theflange to engage tightly in a corresponding groove in the upper face ofthe outer sash.

6. The combination with a window frame and outer and inner slidingsashes, of channel shaped metallic weather strips therefor; one of saidstrips having a body portion, and transversely projecting flanges, theother of said strips having a body portion and a knee-shaped sideflange; beads adapted to retain the body portions of the strips inrabbets provided in the frame, and means for flexing the flanges toengage tightly in corresponding grooves provided in the side and topfaces of the sashes.

7. The combination with a window frame and outer and inner slidingsashes, of channel shaped metallic weather strips therefor; one of saidstrips having a body portion and transversely projecting flanges, theother of said strips having a body portion and a knee-shaped sideflange; beads adapted to retain the body portions of the strips inrabbets provided in the frame, and means for flexing the flanges toengage tightly in corresponding grooves provided in the side and topfaces of the sashes, said means comprising inter-engaging wings on thebody portions and the flanges respectively.

In witness whereof, we have hereunto set our hands at lVashington, D. C.this 13th day of August, A. D. nineteen hundred and twenty-seven.
